Richard Demille Wyckoff (November 2, 1873 - March 7, 1934) was a stock market authority, founder of The Magazine of Wall Street, and editor of Stock Market Technique. Wyckoff implemented his methods in the financial markets and grew his wealth such that he eventually owned nine and a half acres and a mansion next door to the General Motors' Industrialist Alfred Sloan in Great Neck, New York. As Wyckoff became wealthy, he also became altruistic about the public's Wall Street experience. He turned his attention and passion to education, teaching, and in publishing exposés such as "Bucket Shops and How to Avoid Them," which ran in New York's The Saturday Evening Post starting in 1922. Continuing as a trader and educator in the stock, commodity and bond markets throughout the early 1900s, Wyckoff was curious about the logic behind market action. Through conversations, interviews and research of the successful traders of his time, Wyckoff augmented and documented the methodology he traded and taught. Wyckoff died on March 7th 1934 in Sacramento, California. His body was taken to a funeral chapel in Brooklyn, New York.
